Medik8 Crystal Retinal 20 - Firming Skin Regenerating Retinaldehyde Serum - Night Serum with Hyaluronic Acid and Vitamin E - Gluten Free - 1 oz

Visible Results Without the IrritationThis is hands down the best Vitamin A product I’ve used. Medik8 Crystal Retinal 10 delivers smoother, brighter skin with noticeably fewer fine lines—without the dryness or flaking I’ve had with other retinoids. It absorbs quickly, feels luxurious, and the results are real. If you’ve built up tolerance to retinol and want something more powerful yet gentle, this is 100% worth it.

Holy grail product that I will be re-purchasing in the next level once my current tube runs out. I absolutely love this product and my skin feels supple and amazing after using. Make sure NOT to combine with other “active” products like vitamin C or exfoliants. I use every other night in my routine, it layers beautifully, and is perfect.The only downside is it’s a bit pricey, but truly worth it in my opinion.

Medic8 retinal serum improved my skin so much that I can’t imagine going a day without it. Not harsh even for sensitive skin contrary to many other retinol products. Absorbs quickly, doesn’t make your skin dry. Helps prevent breakouts. Don’t forget to use a nice moisturizer with it.

I have rosacea but have wanted to try retinol/retinal. I tried retinol and bakuchiol in the past and my skin didn't like it. Thankfully, no issues at all with this one, and it helped even out my skin a little bit. It was very subtle but that is to be expected with a percentage this low. I have since moved up to Level 3 and when my rosacea is doing really well I can even tolerate Level 6 (but use it on top of a hyaluronic acid serum to reduce irritation). I recommend Level 1 to anyone who is hesitant but curious about retinal.

Best retinal I ever tried.

The dispenser is terrible. It is a pump tube and clogs easily. Had to return first order and second tube pump is just as bad.

That’s really good product

A couple of reviewers commented on the scent and I thought, how bad could it be? Well it's bad. And it's definitely not for sensitive skin. The scent is what I figure made me break out. I have used other retinol products and not had the same problem. Skip this one.
